ELSAG’s Automatic License Plate Reader (ALPR) system, the Mobile Plate Hunter-900 (MPH-900®) automatically records license plate numbers during patrol shifts and compares them to law enforcement databases of vehicles suspected of being associated with illegal activity. If a suspect license plate number is read by the system, audible and visual alarms alert the officer within milliseconds of license plate capture for immediate interdiction. ALPR data can also aid future investigations.
